During the First Presidential Debate (October 3, 2012) I heard Barack Obama mention "10 year old textbooks" in a negative way.
It means that the teacher that I met in Las Vegas, wonderful young lady, who describes to me -- she's got 42 kids in her class.
The first two weeks, she's got them -- some of them sitting on the floor until finally they get reassigned. They're using textbooks that are 10 years old. That is not a recipe for growth; that's not how America was built.
Is there actually any evidence that shows old text books are actually a significant hindrance in a good education?
It seems like older books would correlate with other lack of funding, so it might be a hard to isolate causation or find valid case studies where that variable is even somewhat controlled. But to me it seems most of the stuff I learned in high school hadn't changed in the past 10 years. Have there been any studies?
